Title: Driving turbine with methoxypropanol-water azeotrope - which is nontoxic, nonflammable, noncontaminating, with higher density than steam, and giving more power for same turbine size
Inventor: HEEREN HERMANN
IPC: F01K25/06
Filed: 1976-08-25
Abstract: An azeotrope of water with a mixt. of 80-95% of 1-methoxypropanol-2 and 20-5% of 2-methoxypropanol-1 is used to drive steam turbines or component turbines in turbine systems. The azeotrope contains 53 wt.% methoxypropanol and 47% water. The critical temp. of the azeotrope is 330 plus-or-minus 2 degrees C, and the critical press. is 137 bars. The azeotrope is used pref. in low-press. parts of turbine systems of steam installations, in condensn. turbines, in turbines for heating installations, and in low-press. pts. of installations with two driving means, i.e. where the high-press. part is a normal steam turbine. The azeotrope has higher density than steam, high heat of evapn. and high coefft. of heat transfer in bubble evapn. and film condensn. It is non-toxic, non-inflammable, not too expensive, and non-contaminating for the environment. For a given size of turbine the turbine power is > twice that with steam; for a given power, the size of the turbine is less than half.

Title: Switch control for domestic appliance - uses ten Hz control signal for disconnecting supply at zero load to avoid undesirable electromagnetic fields
Inventor: FALK WERNER ING GRAD
IPC: H02H3/12
Filed: 1976-09-21
Abstract: The controller switches the supply to an installation off at zero load demand, and on again if a load was reconnected. Typically it is applicable to a domestic installation, removes biologically or enrionmentally undesirable electromagnetic field when there is no power demand. The control supply for monitoring the reconnection of a load is low voltage direct current. The circuit may be extended by providing an alternative monitoring supply which is actively biologically beneficial. It is in parallel with the dc supply and an alternative to it, and can be selected at will. Typically the supply is at 10 Hz and produces electromagnetic field strengths of the order of millivolts per meter.

Title: Inlet and exhaust valve actuating cam - has lobed rings guided by sprung plunger to vary lift and timing with engine speed
Inventor: THALHOFER AUGUSTIN
IPC: F01L1/08
Filed: 1976-10-20
Abstract: The inlet and exhaust valve cams are formed as lobed rings able to rotate backwards and forwards on the cam shaft to advance and retard the valve timing. The cam shaft has a radial recess (5) contg. a sprung plunger (6) with a cam shaped end (7) to work with the cam ring inner surface (9). The plunger is lifted in proportion to engine speed variations. A pressure chamber (10) formed in the cam shaft recess (5) has a lubricating oil pressure inlet (11) and outlet to control the plunger lift. The outlet height is varied by an engine revolution speed dependent peg (14). At low engine speed, the plunger face (7) is forced downwards by the force from the rocker arm action on the cam ring lobe and the cam action is retarded.

Abstract: The circuit controls the on and off switching of transistors in switched mode power supplies by rectangular pulses fed over transformers. A control circuit determines the voltage-time area of a switching pulse in the transformer initiated by the leading edge of the rectangular pulse. The next rectangular pulse edge generates through switches a further switching pulse of the same voltage-time area, but of the opposite polarity. Switching elements connect the transformer to a first voltage source when the first leading edge appears and to a second voltage source when the second edge occurs.

Title: Emulsifying residual oil with water - for use as fuel in gas turbine, giving clean, efficient combustion
Inventor: NEALIS CHARLES R
IPC: C10L1/32
Filed: 1977-12-22
Abstract: In the processing of residual oil for use in gas turbines, esp. in jet transmission appts. in aircraft or ships, 3-8 (5) wt.% of water is added to the residual oil, an oil-water emulsion is formed in which the water droplets are dispersed in a continuous oil phase and the emulsion is led to a gas turbine for combustion. Cheap residual oils can be utilised. Overheating of the jet appts. is avoided. The emulsion is stable and can be stored for a relatively long time without sepn. In the gas turbine chamber the water droplets undergo 'micro-explosion' into steam, leading to formation of fuel droplets of 25 mu, compared with 70150 mu in known processes. Complete, clean combustion is achieved in the short combustion chamber of the gas turbine. Addn. of water leads to a water gas reaction during combustion, increasing the combustion efficiency, and also lowers the peak temp. in the combustion chamber.
